Dental implants are replacement tooth roots. They are the closest replacement to natural teeth. They are titanium screws that fuse with bone and are permanent. Advantages of implants are they are the most natural looking, improved speech as they are not removable like dentures, more comfortable, and easier to eat with confidence and without pain. Implants also do not affect surrounding teeth such as bridges which require reducing adjacent teeth. With proper care an implant can last a lifetime.
Once the implant has bonded to the jawbone, a small connector post called an abutment is attached to the implant. An then the replacement tooth, a crown, is attached to the abutment. In some cases the abutments may be used to support a removable denture which allows the denture to stay solidly in place without any adhesives.
